JS WARS is a classic shoot 'em up written to demonstrate the power of modern Web browsers. It is targeting Firefox 3.5 with its audio/video support and increased performance, and uses the canvas tag. It should work well in other modern Web browsers (supporting the canvas tag), just without the music and sound effects.

The TellurianRing Scene project is a JavaScript animation library built primarily on top of the HTML 5 Canvas element. It aims to provide a simple but descriptive and powerful domain specific language (DSL) to describe a SceneGraph by exposing and simplifying the functionality of the Canvas element. Canvas and Scene make it easy to create Web animations in the browser without the need to download any plugins.

noVNC is a VNC client implemented using HTML5 technologies, specifically Canvas and WebSockets. It supports "wss://" encryption (SSL/TLS). For browsers that do not have native WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. In addition, as3crypto has been added to web-socket-js to implement WebSocket SSL/TLS encryption, i.e. the "wss://" URI scheme.

Cacophony is a tool for creating and viewing interactive videos, especially music videos, using HTML5 video and canvas elements and Javascript. Interactive elements include visuals/story adapting in response to user input as text, mouse movement, drawings, and choices (choose-your-own-adventure). Input from the viewer can affect the subsequent video, and also be sent to a server for integration with other Web applications (social networking, sharing, and geotagging), which is possible because effects are rendered on-the-fly in the browser, not pre-rendered like traditional video. Input can also come from external sources (RSS and JSON), so you can integrate external data, or previously generated data, back into subsequent views of the video.

jsGameSoup is a framework for making games for the Web using JavaScript and HTML5. It abstracts away some of the complexity of developing Javascript games for multiple browsers. It currently runs under new versions of Firefox (Gecko), Safari/Chrome (WebKit), and Internet Explorer 6 and higher. It does not require any proprietary technologies like Flash or Silverlight.

Easy Chart is an object to display several types of charts in Canvas elements. It takes the values, labels, and colors of each point and renders the chart in canvas elements of a given size. Currently, it supports rendering charts of types: line, scatter, column, bar, and pie. The chart background color, grid color and spacing, error, and mouse event handlers are configurable parameters.

Canvas Events is an object that can emulate mouse events on canvas elements. It extends the HTML 5 canvas context object for a given canvas element, and can register event handlers to be called when mouse events on the canvas element occur. Currently, it supports the events click, dblclick, mouseover, mouseout, mousemove, mouseup, and mousedown events.

Canvas Turtle is an object that interprets and renders graphic commands in a Canvas. It provides an API for rendering basic drawing primitives in 2D and includes commands that define the position of the graphics to be rendered, conditionals, loops, and so on. Commands are supplied as text strings with a simple syntax.

Canvicon sets the current page's favicon to a canvas image. It takes the identifier of a canvas element on a page and sets the favicon to the image currently rendered in the canvas. It is available either as a standalone object or a jQuery plugin.
